OBJECTIVES: Students should be able to...
Define and identify the major concepts of the experimental design of an experiment
Independent variable (IV): the variable that is purposefully changed by the experimenter.
Dependent variable (DV): the variable that responds.
Constants (C): all factors that remain the same and have a fixed value.
Control: the standard for comparing experimental effects
Repeated trials: the number of experimental repetitions, objects or organisms tested at each level of the independent variable.
Experimental Design Diagram: a diagram that summarizes the independent variable, the dependent variable, constants, control, number of repeated trials, experimental title, and hypothesis.
